    Episode Notes

    Les Johnson has spent his life working with NASA to realize advanced propulsion concepts that could one day enable interstellar voyages. In a new volume, the Interstellar Travel Monograph, he and a select group of experts explore all of the challenges such a voyage would present, before, during, and upon arrival.

    Episode Notes

    The decision to name the Next Generation Space Telescope after former administrator James E. Webb has led to significant controversy and demands that it be renamed. This issue has shone a light on a dark period in the history of the U.S. and NASA and has raised questions about the agency's naming conventions.

  • Episode 106 - Megastructures (Part III)

    Episode 106 - Megastructures (Part III)
    2025/08/05
    Sixty years ago, famed physicist Freeman Dyson theorized that advanced civilizations, in their ongoing quest to find more living space and energy, would convert their solar system into a megastructure enclosing their star. This gave rise to the concept of megastructures, many of which have been theorized over the years. These hypothetical structures are one of many technosignatures SETI researchers are on the lookout for as they probe the stars for signs of intelligent life.

  • Episode 104 - Megastructures!

    Episode 104 - Megastructures!
    2025/06/25
    In the Search for Extraterrestrial Intelligence (SETI), scientists need to consider what technologies they should look for, including those used by a more advanced species. This has spawned the idea of Megastructures, which was first proposed in the 1960s by theoretical physicist and mathematician Freeman Dyson (who proposed the Dyson Sphere). Since then, many variations and other possible Megastructures have been proposed, all of which are fascinating and fun to think about!

    Episode 102 - My Interview with AADYA Geo Talks (Part II)
    2025/06/06
    A few months ago, I had the honor of appearing on AADYA Geo Talks, the podcast series launched by Bharti Sharma and the organization she founded – AADYA, whose name means “origin” in Hindi. As a geologist and world-traveller, Sharma launched this organization to promote knowledge about planetary and geoscience and create opportunities for collaborative research to address critical global challenges. During the interview, we talked about how I got into science journalism, my podcast series, and my science fiction writing. The interview lasted for more than an hour because she asked great questions about a range of wonderful topics!
